fluidSource - The fluid source to fill from

inventory - An inventory where any additionally created item (filled container if multiple empty are present) are put

maxAmount - Maximum amount of fluid to take from the tank.

player - The player that gets the items the inventory can't take. Can be null, only used if the inventory cannot take the filled stack.

Returns:

a FluidActionResult holding the result and the resulting container. The resulting container is empty on failure.
